SPECIFICATION forming part of Letters Patent No. 601,920, dated April 5,1898.

Application filed June l, 1897.' Serial No. 638,848. (No model.) I

To all whom it may concern.-

Be it known that I, MILO LUTHER GATES WHEELER, of North Yakima, in thecounty of Yakima and State of Washington, have invented certain new anduseful Improve- :ments in Pumps; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to improvements in lifting-pumps, and hasreference to that class of pumps whereby a column of water is raised ordirected to any desired point by the action of compressed air orsteam-pressure.

The invention consists in the novel features of construction hereinaftermore particularly set forth and claimed.

In the accompanying'drawings, forming a part of this specification,Figure 1 is an elevation. Fig. 2 is a top plan view. Fig. 3 is avertical sectional view of Fig. 1. Fig. 4. is a sectional detail View ofthe barrel-casing of i the valve for controlling the admission of air tothe tanks. Fig. 5 is detailview of the Valve. Fig. 6 is a sectionaldetail view of the valve-casing and valve controlling the admission ofair to the cylinders. Fig. 7 is a detail view of the valve andoperating-arm, and Fig. 8 is a detail View of the arm for operating saidvalve.

Referring to the drawings, A is a casing which is divided by atransverse partition into the two compartments or tanks A A said casingbeing supported upon suitable skids 1.

Each compartment or tank isprovided with a dome Q,having-the tops orcovers g, through which extends a tube M, which terminates a shortdistance from the bottom of each tank,

said tube servingas a guide for the vertically-moving rods M, having ontheir lower ends the plates P. Freely movable upon each tubular guide Mis a float L, whose movement is effected by the rise and fall of theWater within the tank.

I is a pipe leading from an air-compressor (not here shown) and unitedat its lower end to the five-way coupling J, which constitutes thevalve-casing for the valve K, which is movable therein. Pipes I and Icommunicate with the respective tanks A and A at their lower ends and attheir upper ends unite with the five-way coupling at the points d d. Thetwo remaining openings of the five-way coupling e 6 receive theexhaustpipes f, which may be connected with a receiver upon the surfaceand to the air-compressor, the same not being here shown, so as to forma complete circuit, and thus the air exhausts under a full pressure andgradually decreases to the atmospheric pressure which will serve toassist the power driving the aircompressor, thus effecting a saving insaid power.

S S indicate two cylinders which are connected together by the castings, which constitutes one member of the clamp by which the cylinders aresecured to pipe P, a yoke s encircling the pipe and being united to thecasting by securing-bolts. Movable within these cylinders are thepistons T, which are connected together by the piston-rod T, so thatthey move in unison.

2 are vertical pipes which communicate at their lower ends withcylinders S S adjacent their outer ends and 'at their upper ends engageone of the openings of the three-way couplings t t, while horizontalpipes or; m are also united to the three-way couplings and at theirupper ends communicate with pipe 1 Intermediately pivoted to thecoupling which unites the pipes at as to the pipe 1 is the lever 0,having the rods N N pivoted at their upper ends to its opposite ends andat their lower ends secured to the coupling sleeves y, through which theupper ends of rods M extend, and are secured by set-screws M Thethree-way couplings t and 15 form valve-casings for valves V and V,which are concave, as illustrated, and which are provided with concavedepressions which are adapted to register with pipes 2 and m or m orwith pipes 2 and the exhaust-openings 3 in the three-way couplings. Thestem of each valve projects through the coupling and has secured theretothe operating-arm W, carrying at its outer end the pin W, which isadapted to engage the slot 0 in the end of said lever. It will benoticed that these arms extend in opposite directions from each otherand that as lever O is operated the valves V and V alternately openand-close communication between the pipes 2 and a; 0c.

Springs u are positioned upon the valve-stems on the opposite side ofthe couplings between the ad justin g-nuts and the outer walls of thecouplings, so that the valves are held firmly at all times to theirseats.

The main valve K is provided with a central passage a b and has itsopposite sides provided with the concaved depressions c 0. Secured atone end to the valve K is the arm 9', which is slotted at its upper endto receive the pin 7", carried by the piston-rod T, so that the movementof the pistons will operate said valve to cause it to establishcommunication alternately between the pipes I and I and I and I and alsowith the respective exhausts c. This valve is also provided with thespring a for the purpose of holding it firmly to its seat.

H H are outlet-pipes which communicate with the respective tanks A A andhave secured thereto the valve-casings G G, in which are located thevalves F F. Secured at one end to the valve-casing G is thedelivery-pipe E, while secured to the valve-casing Gis the delivery-pipeE, said pipe communicating with pipe E: I

O C are the water-inlet pipes, provided with the inclined valve-seats CC and the valves D D.

4 4 are vertical pipes which communicate at their lower ends with domesQ Q and at their upper ends with the horizontal pipe 5, whichcommunicates with pipe E. The pipe 5 is provided with a stop-cock 6,while pipes 4 are provided with the valves 7.

As illustrated in Fig. 3, communication is closed between thecompressed-air supply and pipe I,while communication is establishedbetween the same and pipe I, thus conveying the air to tank A. Thepressure of the air upon the water forces the latter upward through theoutlet-pipe and delivery-pipe E. As the water lowers in the tank, floatL follows the same downward, and when the latter comes in engagementwith the plate P its weight will move the rods M N downward, causingthat end of the lever O to which they are secured to be depressed,raising its opposite end. This movement of the lever through the mediumof the short arm W moves the valve V, so that it closes communicationbetween the pipes 2 and w and permits the air in the cylinder S toexhaust through ports 3. At the same time valve V is moved to establish.communication between the pipes 2 and 0c and close the exhaust, so thatair is admitted in the cylinderS and moves the piston T toward theopposite cylinder, which, through the medium of the connection betweensaid piston T and the arm 7", moves valve K to close communicationbetween the pipes I and I and establish it between the latter and pipeI, so that air is admitted to tank A which has filled with water duringthe emptying of tank A. It will be understood that the movement of thelever 0 also moves rods M and N and returns plate P to its normalposition.

By having a connection between the domes of the tanksand pipe E aportion of the air may be admitted to the discharge-column of water,thereby lightening the water column proportionately to the volume of airadmitted, and thus raising the water to a much greater height with agiven air-pressure from the aircompressor than obtained by forcing asolid column of water in the pipe. This construction is especiallydesirable in discharging the water from deep mines, although for thischaracter of work the pump may be operated in relays and greater liftingforce may be obtained for each pump, and therefore requiring a smallnumber of relay-pumps.

My pump may be operated by any power suitable to operate anair-compressor and is adapted for use as a deep-mining pump as well asfor hydraulic mining, and it is adapted to receive water from anysupply, conveying it directly to the desired point without the necessityof building expensive ditches or troughs, only to be abandoned when theclaim is worked out. This pump is also adapted for irrigation and may beoperated by a windmill power, as will be understood.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
